Irrlicht Engine

I solved most of the problems... just one left. I'm using b3d pipeline.
How can I just set a color to a mesh from the map?
How can I apply a glass material to a mesh from the map?
Irrlicht doesn't seem to read the alpha value from the b3d material.

I figuread that about short time ago. The octtree past doesn't seam hard. B3d doesn't know of normal maps, and neither does obj. Does x sport that?. I'd like to use normal maps on most of the walls/floors.

I have a level in 3d max. I'd like to export it to irrlicht somehow to be able to walk around in it. BSP's seams not to be the answer since If I'd use them I'd have to remake everything in GTkRadiant or so. Is it possible to export to b3d (or something that saves mapping) and add it to a irrlicht sc...

I tried the part with setInputReceiverEnabled() but that one stops all input and I'd just like the mouse to be disabled...

How could I posibily do that?
I want to look around with the mouse only when it's clicked and when not to be able to freely use the mouse to click objects.
I took a look at the functions inside the ICameraSceneNode and coudn't find what I'm looking for.
Thank you!
